The short explanation
Healthy kidneys make a hormone called erythropoietin, which tells the bone marrow to produce red blood cells. When the kidneys are damaged, they make less of this hormone, so the body makes fewer red cells even if there is enough iron. This is why anaemia is common in people with long-term kidney disease, and why iron alone often is not enough. Treatment usually aims to correct any iron shortage first, then, if needed, a kidney specialist may suggest an injectable medicine that does the job of the missing hormone. The plan depends on her kidney function, haemoglobin level, symptoms and other conditions.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- People with kidney disease are often also low in iron or B12, so these are usually checked too.
- Diabetes and high blood pressure, common causes of kidney disease, also need good control to protect the kidneys.
- Regular blood tests help her doctors adjust treatment over time.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what treatment is right for your mother. Her kidney specialist will decide based on her tests and overall health.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is her iron level also low?
- Would she benefit from the hormone treatment for anaemia?
- How often should her haemoglobin be checked?
- What symptoms should make us bring her in sooner?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 if she has chest pain, severe breathlessness, confusion or fainting.
Get help the same day
- Get care the same day if she has much less urine, swelling of legs or face, or vomiting.
Raise it at a routine appointment
- Keep her regular appointments with the kidney specialist.
